xorg.conf needed option to maximize compiz performance.

Hi,
I'm using Fedora 8 on an Acer Aspire 5920G Gemstone using 8600M GT
with 100.14.19 driver.

here my xorg.xonf

Code:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig

# nvidia-xconfig:  version 1.0  (buildmeister@builder26)  Wed Sep 12 14:29:17 PDT 2007



# Xorg configuration created by pyxf86config

    EndSubSection

EndSection

EndSection

Is there some option that I need to remove or add to maximize compiz performance?

Is this extra option useful?
Option "AddARGBVisuals" "True"
Option "RenderAccel" "1"
Option "AllowGLXWithComposite" "1"
Option "NoRenderExtension" "0"
Option "XAANoOffscreenPixmaps" "1"
Option "TripleBuffer" "true"

With my xorg.conf compiz works really fine but euphoria screesaver for example seems to slow down quite often.

Thanks!

PS: I've just tested al 169.04 driver with the same xorg.conf posted before and it runs slow also with this beta driver.
Euphoria screensaver is slow. :(

Euphoria screensaver is slow. :(

I have ubuntu 7.10 and this is my Device Section

Code:

Section "Device"

        Identifier        "nVidia Corporation G80 [GeForce 8600 GT]"

        Driver                "nvidia"

        Busid                "PCI:1:0:0"

        Option                "AddARGBVisuals"        "True"

        Option                "AddARGBGLXVisuals"        "True"

EndSection

I don't have this settings in my xorg.conf

Option "XAANoOffscreenPixmaps" "1"

Section "Extensions"
Option "Composite" "Enable"
EndSection

Maybe you should ask in a Fedora Forum for help.
It seems for me that this is a distribution specific problem.

What also would be interesting is, with what options fedora starts compiz.

I hope this helps.

In that way is also slower :(
I can't understand where is the problem :(
